Magnets in Orthodontics

Magnetism is a virtue that drives the contemporary society. From the earth¿s revolution around the sun, to the universe swaying to charms of Indian beauties, magnetism exemplifies its experience .Orthodontics and craniofacial orthopaedics are therapeutic approaches that modify the occlusion, facial form and function through the application of prolonged, mechanical forces. Traditional force delivery systems in orthodontics include the use of wires, springs and elastics. Alternately, magnetic forces can be used to generate the force for tooth movement and orthopaedic treatment. Advantages of magnetic force delivery include good force control at short distances, no friction, and no material fatigue. Magnetic forces have been used in orthodontics for both tooth movement and orthopaedic correction with varying degrees of success. Magnetic systems permit precise control of the force levels that are applied, as the force generated can be calculated from specific force-distance diagram.
